We're dividing 45847290 by 800 
The aim is to understand the frequency of 800 in 45847290.

Advancing to step 1:
The number 800 fits into 4 0 times, leaving a remainder of 4.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 4, we end up with 4.
Append the next digit (5) from the dividend to 4 and continue with: 45 / 800

On to step 2:
800 goes into 45 0 times with a remainder of 45.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 45 leaves us with 45.
Bring next digit (8) of the dividend behind the 45 and repeat the process: 458 / 800

Moving on to step 3:
When dividing 458 by 800, we get 0 with a remainder of 458.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 458 after subtracting 0 from 458.
Take the next digit (4) from the dividend and append it to 458, then repeat: 4584 / 800

Moving on to step 4:
800 can be fit into 4584 5 times, resulting in a remainder of 584.
The next digit of our result is 5. 
Result so far: 5.0
The remainder is 584 after subtracting 4000 from 4584.
Grab the next digit (7) from the dividend, add it to 584, then carry on: 5847 / 800

Going ahead to step 5:
If we divide 5847 by 800, we get 7 and a remainder of 247.
The next digit of our result is 7. 
Result so far: 57.0
The remainder is 247 after subtracting 5600 from 5847.
Fetch the next digit (2) from the dividend, attach it to 247 and continue: 2472 / 800

Let's proceed to step 6:
When dividing 2472 by 800, we get 3 with a remainder of 72.
The next digit of our result is 3. 
Result so far: 573.0
If we subtract 2400 from 2472, we get 72.
Bring next digit (9) of the dividend behind the 72 and repeat the process: 729 / 800

Moving on to step 7:
800 goes into 729 0 times with a remainder of 729.
The number 0 becomes the next digit in our result. 
Result so far: 5730.0
Subtract 0 from 729 to get 729.
Grab the next digit (0) from the dividend, add it to 729, then carry on: 7290 / 800

Advancing to step 8:
The number 800 fits into 7290 9 times, leaving a remainder of 90.
The number 9 becomes the next digit in our result. 
Result so far: 57309.0
The remainder is 90 after subtracting 7200 from 7290.
Since there are no more digits in the dividend, we add a zero to the remainder making it 900, and continue the process.

Let's proceed to step 9:
900 divided by 800 is 1 with a remainder of 100.
The next digit of our result is 1. 
Result so far: 57309.1
Subtract 800 from 900 to get 100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1000, and continue the process.

Let's proceed to step 10:
800 can be fit into 1000 1 times, resulting in a remainder of 200.
The next digit of our result is 1. 
Result so far: 57309.11
Deduct 800 from 1000 and we're left with 200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2000, and continue the process.

After the division, we end up with 57309.11 and a remainder of 0.2.
